HOT-WATER STOVE.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed July 2, 1913. Serial No. 776,894.

To all whom it may concern:

Be it known that I, SAMUEL V. Rnnvns, a citizen of the United States, residing at Haddonfield, county of Camden, State of New Jersey, have invented a new and useful Hot- VVater Stove, of which the following is a specification.

My present invention relates to a hot water stove which is adapted to be used on water pressure systems as well as on closed and open tank gravity systems.

With the above in view, my invention in its broad and generic scope, consists of a novel construction of a heating stove, wherein is employed a novel type of water jacket.

It further consists of a novel construction of a water jacket or cored chamber, which may be rotatably adjusted in order to make the proper connections therewith.

It further consists of a novel construction of a stove of the character described, in

which a core or jacket of novel construction is employed, whereby a maximum amount of water is heated with a minimum consumption of fuel.

It further consists of a novel construction of a water jacket wherein the water chamber has a lesser internal diameter near the grate line than it has for a predetermined distance above the grate line.

It further consists of a novel construction of a water jacket wherein the outer wall of the water chamber is at an angle to the inner wall thereof.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawing a typical embodiment thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

The accompanying drawing represents an elevation, partly in section, of a heating stove embodying my invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: In heating stoves of small size, wherein the water cham ber of the jacket is of uniform diameter, considerable difficulty has arisen in maintaining the fire owing to the large volume of water surrounding the fire which tends to deaden the same. In former devices it has been deemed necessary to construct the fire chamber beneath the water jacket the result of which is that the heat which should be imparted to the water is radiated into the room. In accordance with my present invention, the water jacket is cored into close proximity with the grate line and has a lesser diameter at such point than is given to the water jacket at a point located above the bed of fuel. lhe stove, base, and the grate may be of any desired or conventional construction, and the top may also vary widely in practice, and in the present instance, I have shown the base portion 1 supported in any desired manner and provided with a laterally extending annular flange 2 and a grate 3, which latter is supported on a shoulder 1 formed within the base.

5 designates the water jacket which in Fig. 1 is provided with an inner cylindrical wall 6, illustrated as substantially vertical and having formed therewith an outer wall 7, which latter is outwardly deflected toward its central point to form angularly inclined sides which are united at 9, at which point the water jacket chamber has its greatest internal diameter.

10 designates a conduit communicating with a source of water supply, such as for example, a water pressure system or a closed or open tank gravity system, it being understood that the water may pass through the conduit 10 under any desired pressure, said conduit communicating with the interior of the water jacket near the lower end thereof.

11 designates a discharge conduit communicating with the upper part of the internal chamber thereof and leading to a desired point of utilization. The water jacket, at its lower end, is provided with a laterally extending lug 12, which is connected with the flange 2 of the base by means of fastening devices 13 of any desired or conventional t e.

he inner bore of the water acket 5 at its upper end may be outwardly flared, as at 14:, and may be recessed on its outer periphery to form an annular shoulder 15 adapted to support a top casing 16 having any desired contour and which, in the present instance,

of the waterjacket is intermediate the ends ,in the well known manner.

is provided with a sectional cover 17 having portions 18 thereof adapted to be removed The cover 17 is also provided with a collar 19 to which is connected in the usual manner a smoke-pipe through which the unconsumed products of combustion pass from the stove to the chimney or other desired point of discharge. will thus be seen that the water jacket in Fig. 1 has'the formatio-n' of a double V- shaped core with the open ends of the unitedso that the greatest internal diameter thereof. If desired, theouter wall of the water jacket may be provided with radiating ribs 2 V V I have disclosed a water jacket, the internal diameter of the water chamberof which is lesser; near the grate line than it is-above the bed of fuel and; which for a predetermined distance above the. grate line gradually increases. It will be understood by those skilled in this art that I provide the 'largest volume of water at the. point at which the greatest amount offheatisproaduced by the'bed of fuel.

Water jackets constructed in accordance .with my invention, as herein disclosed,have

givenmarked and advantageous results, in

. practice, and it is possible; to heata very large amount of liquid with a very small I easy maintenance of a fire of the smallest size. In devices'of this character as heretofore-constructed, considerable difficulty has arisen in main-taming a fire inhot water stoves of small size, such asfor' example twelve inches or lessiin diameter andby the employment .of my present; invention this difiicultyhas been wholly overcome.

. I am aware thatit has heretofore been I proposed to employ in a domestic boiler a conicalfire pot having a water chamber therearound whose greatest diameter is placed nearest the upper end thereof and in 7 conjunction with which there is employed aconical damper to divide the-outgoing products ofcombustion. My present invention is differentiated therefrom since I employ a water jacket wherein the inner survface thereof is of substantially uniform diameter while the outer wall of said jacket 7 has its greatestdiameter at'the medial point equidistant from the top and bottom, the upper, outer, annular wall of said jacket convergingupwardly from said medial point and the lower, outer, annular wall thereof converging; downwardly from said medial point, the inclination of said upper and lower; walls with respect to the longitudinal axis of my novel jacket being substantially the same.

By reason of the foregoing construction, it will be apparent that the hottest portion of the fire will be at about the middle of the water jacket, where the area of the body of the water is transversely the greatest, the cooler portions of the fire-pot being at the bottom and at the top where the body of minate temperature in the whole water chamber, whereas in the prior art devices to which I have referred, there would be three separate and distinct temperatures of the water, the result ofwhich would be to tend to retard the movement or circulation of the water.

It will now be apparent that I have devised a novel and useful construction of a hot water stove which embodies the features of advantage enumerated as desirable inthe statement of the invention and the above description, and while I have, in the present instance, shown and described those preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my inventionwhat I claim as new and desire to secure by Letters Patent, is

1. In a device of the character stated, a water jacket for a fire-pot, having its, interior of uniform diameter and unobstructed, the outer wall of said jacket having its greatest diameter at a medial point equidistant from its top and bottom, and the upper, outer, annular wall of said jacket converging from said media-l point upwardly towardsaidtop, and the lower, outer. annular wall thereof converging downwardly from said medial point toward said bottom, the inclination of said upper and lower walls with respect to the longitudinal aXisof said jacket being the same.

' 2. In a device of the character stated, a water jacket for a fire-pot, having its interior of uniform diameter and unobstructed, the outer wall of said jacket having its greatest diameter at a medial point equidistant from its top and bottom, and the upper, outer, annular Wall of said jacket conversing from said medial point upwardly toward said top, and the lower, outer, annular wall thereof converging downwardly from said medial point toward said bottom, the inclination of said upper and lower walls with respect to the longitudinal axis of said jacket being the same, a support for said Water jacket, a grate carried by said support in close proximity to 19 the lower water line of the jacket, and a top casing extending outwardly therefrom and supported above said water jacket.
